# Math Help - Regression chart Analysis

1. ## Regression chart Analysis

Can someone please help me with this problem, I do not know where to look for the answer on the chart. The chart is in the attachment folder.

2. The test to kill all three variables in one step is the F test with test stat 12.82165585 and you compare it to an $F_{3,36}$.
The p-value is $P(F_{3,36}>12.82165585)$ and the printout gives that value as 7.48476E-06.
So as long as $\alpha>7.48476E-06$, you reject $H_0$ which is that all three variables can be dropped.
But with such a small p-value the conclusion is that we do indeed need at least one of those three terms to explain these people's salary.
